The fuselage construction was of fabric over a steel-tube framework, and the wings were of fabric-covered wooden spars and metal ribs.
Variants
;PJ-260
;D-295 Senior Aero Sport: A two-seat derivative of the original PJ-260 that was marketed to home builders from the mid-1960s onwards. Early examples were distinguished as D-260 for those powered by the same 260 hp
Lycoming O-435
The Lycoming O-435 is an American six-cylinder, horizontally opposed fixed-wing aircraft and helicopter engine made by Lycoming Engines. The engine is a six-cylinder version of the four-cylinder Lycoming O-290.

Lycoming O-360
The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines. Engines in the O-360 series produce between 145 and 225 horsepower (109 to 168 kW), with the basic O-360 produci ...
. Work on two prototypes commenced in 1964, but was not completed by the time the more complete of the machines was damaged in a fire in 1973. Work resumed in 1975, but was suspended in favour of the D-201 Sportwing.
;D-260
;D-201 Sportwing: Like the D-260, a two-seater. It was developed in 1977 with the intention of simplifying construction of the aircraft for homebuilders, as well as reducing the weight of the design. The prototype flew in or around 1981, and five sets of plans had sold by 1984.
